Alaska’s lieutenant governor signed into law rules to allow on-site consumption of marijuana at some licensed retailers, becoming the first state to legalize social cannabis consumption.

The move to approve an on-site consumption program could generate up to $2.4 million in new revenue in the state, according to an informal industry analysis.

“When these rules go into effect, Alaska will be the first state to finalize and approve statewide rules for on-site consumption. We expect more to follow suit in the not-too-distant future,” NORML Executive Director Erik Altieri said in a statement.

The rules will go into effect April 11, the Juneau Empire reported, but local governments can ban on-site consumption through ordinance or a voter initiative.
